[Spridgets] primers....thinking out loud

[Bud Osbourne]

Thanks, Frank.  Keeping in mind that this discussion is for the
underside, only; I've already got the dust situation well under control.
The general consensus is that the PPG product can/has been successfully
used with just a good "solvent wash".  My solvents of choice are Dupont
3919S, followed by lacquer thinner.
Re: the body filler over self-etching primers.....I've long since
mis-placed the instruction/data sheet for Variprime, so I have no way to
confirm that.  However, I'm going to follow your recommendation and stay
away from the self-etching primer (even though I won't be using any body
filler on the underside).
As far as base-clear vs. single stage is concerned, I'm not real
concerned with duplicating the original finish, and I've been very happy
with the two base coat-clear coat lacquer paint jobs I've done, as
opposed to acrylic enamel, or single stage lacquer.  Since this one will
be Glacier White, I'm fairly comfortable with future repairs, given
white's wonderful ability to hide repairs/imperfections.  Also, this is
a "driver", first and formost, so I'm not concerned about a few paint
chips gained from hard driving ;)
The guy I learned painting from, years (now decades !!!) ago, has been
urging me to try the new acrylic enamels (or whatever they've been
replaced with) since 1990.  However, I have found the acrylic lacquer to
be durable enough for my purposes, as well as MUCH easier to live with
in my workshop (clean-up issues, primarily).  So, until the enviro-nazis
pry the acrylic lacquer out of my cold, dead hands (or I can no longer
find the stuff); I'm stickin' with it.

The soap and water wash is to clean the dust off the car.
You can use final prep or wax/grease remover instead.
Also watch the etching primers, they do not like body filler over 
etching primers. Or so the label says.
I etch, epoxy, then surface/filler prime.
Also give long hard thoughts to a base/clear paint job.
Touch ups are near impossible or very time consuming.
My son was a base/clear man for a few years but WHEN, not IF the base 
clear got a chip or scratch, the touch up was worse than the damage.
Now he, like me, use the single stage urethane paint.
Need a scratch or chip touched up, just do it and wet sand the spot the 
next day, you never see it.
But, I am just thinking out loud Bud, just letting you know what I have 
learned about base/clears. I wish my Jag was never clear coated because 
now 4 years old, there are chips in the clear and it's just not possible

to touch it up and make it look good.
Just think, the car is all painted and shiny and during assembly you 
slip with a screw driver or wrench and chip the paint where the mirror 
goes on the door. Gawd I hate it when I do that! Good thing it was 
single stage.
